If the vehicle is equipped with the func-
tion, this system monitors the tyre pres-
sure.
Operating principleEach wheel (except for the emergency
spare wheel) has a sensor in the infla-
tion valve which periodically measures
the tyre pressure. The system informs
the driver via the display 1 and on-
board computer 2 that the tyres are suf-
ficiently inflated and warns if they are
underinflated or leaking. The warning
light 4
on the instrument panel
comes on to warn the driver if the pres-
sure is too low. It should always be done after checking
the tyre pressure of all four tyres when
cold.
Tyre pressures must correspond to the
current usage of the vehicle (empty,
carrying a load, motorway driving, etc.).
With the ignition on:
– Make short presses on the control
3
to select the tyre pressure display
(see “On-board computer: settings”
in Section 1);
– press and hold (around 3 seconds) the button 3 to launch the reset. A
flashing tyre followed by the mes-
sage “Pressure ref Ongoing” indi-
cates that the request to learn the
reference pressure has been taken
into account;
– reset can take several minutes of driving.

Resetting the standard level
for the tyre pressures
This should be done:
– when the standard tyre pressure needs to be changed to adapt to
usage conditions (empty, carrying a
load, motorway driving, etc.);
– after swapping wheels over (how- ever this practice is not recom-
mended);
– after changing a wheel.
This function is an addi-
tional driving aid.
However, the function does
not take the place of the
driver. It cannot, therefore, under
any circumstances replace the vig-
ilance or the responsibility of the
driver.
Check the tyre pressures, including
the emergency spare wheel, once a
month.

TYRE PRESSURE MONITORING SYSTEM (3/4)
“CHECK TYRE PRESSURE
SENSORS”
The warning light
flashes for
several seconds, then stays on, along
with the message “CHECK TYRE
PRESSURE SENSORS” and a missing
wheel B.
This message appears along with the
© warning light.
This message appears when at least
one wheel fitted on the vehicle does not
have sensors (e.g. emergency spare
wheel). In other cases, contact an au-
thorised dealer.
Replacing wheels/tyres
This system requires specific equip-
ment (wheels, tyres, sensors, etc.).
Contact an authorised dealer to replace
the tyres and to find out about avail-
able accessories compatible with the
system: the use of any other accessory
could affect the correct operation of the
system or damage a sensor.
Changing a wheel
The system may take sev-
eral minutes depending on
use for the new wheel po-
sitions and pressures to be recog-
nised; check the tyre pressures after
all operations.

Interchangeability of wheelsIf you wish to swap the wheels around,
please consult an approved dealer to
reinitialise the system.
Each of the sensors incor-
porated in the valves 5 is
dedicated to a single wheel:
under no circumstances
should you swap the wheels, with-
out resetting the system.
There is a risk of incorrect informa-
tion which could have serious con-
sequences.
